Have you looked at the Lite5200B schematic to see where the signals in question go? Maybe you trying to drive something tied to ground high or vice-versa.

Hi all, I not pretty sure if this is the correct forum to ask for a solution but I know that some of you have worked on a driver to make PSCs in this board work in an I2S mode. Have you ever have powerfail problems when writing the configuration registers for this mode? I´ve delimited the problem: - GPIO Port Config register stores without problems the value "111" in bits 25:27 (PSC2 to work in CODEC2 functionality with MCLK). - When I write a "1" in PSC2->SICR register bit GenClk to ensure that clock and FrameSync are generated internally from MCLK the systems suffers a powerfail and I suppose that´s consecuence or some kind of shortcircuit. I´ve followed the same steps made by Bob Peterson in http://ozlabs.org/pipermail/linuxppc-embedded/2005-September/020210.html to write the configuration in the proper registers but I still suffer the powerfail when GenClk is activated or, if I activate that bit first, when Port Config is written. I´m also trying to understand how things are done in Roman Fietze driver but can´t find a difference. That makes me think that perhaps other registers must be modificated before driver loading. Meanwhile, I keep waiting for Grant Likely release, :-). Has this happened to someone before? Thanks for your help.
